Human rights investigators have released their latest report on Syria, including their findings on the Houla massacre.

A commission of inquiry, which has been investigating human rights violations for the UN Human Rights Council, says that what began as government suppression of peaceful demonstrators has turned, in many areas, into civil war.

The Geneva-based UN council called on the commission earlier this month to find out who carried out last month's killings in Houla in which 108 people died.

UN investigator and author of the report Karen Abuzayd told the BBC that "there is the possibility of three different groups who may have done this".

She said that government forces were responsible for the initial shelling in which some people died. But what she called the "massacre" afterwards in people's homes was done either by militiamen from Alawite villages - known as shabiha - or possibly by armed opposition groups.
